Answer:

c) when the blood sugar is to low, the body sends hormones the raise blood sugar until it reaches a typical level and hormones secretion slows.

Explanation:

  • The function of a negative feedback loop is to reduce the output of a system. In the endocrine system, negative feedback stops or decreases the production of a hormone that is no longer needed.
  • This is the case with the hormones that regulates the level of glucose in the body. When the blood sugar level is low, the pancreas is triggered to secrete the hormone glucagon which helps raise the level of blood sugar, until a certain level and the secretion of the hormone slows.
